Schematic overview of the Continuous Visual Attention attentional test (CVAT): (a) the CVAT starts with on-screen instructions: “In this test, the computer alternately displays the indicated figures in the center of the screen. You must press the spacebar using your dominant hand as fast as possible whenever the star appears in the center of the screen. If the other figure appears, you should not press the space”. (b) The target (star) remains on the screen for 250 ms. (c) The non-target (diamond) stays on the screen for 250 ms. Variables provided by the test: average Reaction Time of the correct responses (RT), Intraindividual Variability of Reaction Time (VRT = standard deviation of the RTs during the test), Omission errors (OE), and Commission errors (CE). The CVAT is available for research and clinical use (licensed psychologists) upon request of Prof. Sergio L. Schmidt. The test is available in English, Spanish, and Portuguese.
